.-fIMPRovEMENT IN wlNDow-BLINDS.

' Speciication forming part of Letters Patent No. 175,236, dated March 28, 1876 application led V February 28, 1876. V

Be it known that I, JEREMY W. BLIss, of the city and county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Window-Blinds and Device for Operating their'Slats 5 and to enable others'- skilled in the art to make and. use the same I will proceed to describe,re ierring to the drawings, in which the same ures.

The nature of this invention will be understood frolnthe? specification and drawings.

` `Figures l and 2 show the inner edgev of a blind-stile, vhaving a removable slat holding and operatingA case and removable slatholdin g stop, secured in rabbets formed therein, so that the slats may be readily removed from the frame when desired. Fig. 3 shows a portion of a case made in two parts, for the purpose of allowing the gears-to be secured upon the. ferrule 'beforethey areY arranged in the` case. Fig. 4 shows a slat broken near its center, having a flanged ferrule and toothed gear fixed upon oneof its tenother end. Fig. 5 shows an end view of'a slat and ,its tenon, and a side and end view of a bushing arranged in the stop, Vand in Fig. 6 shows a cross-V section through one of the slats,` with side and edge views of the tlange-ferrule, with and ais a blind-frame stile. b is a removable stop, fitted and secured in a rabbetformed in the edge of the stiler In the face of this stop orifices or bearings are made for the| slattenons. These orifices or bearingsV are made to receive the slat-tenons, with orwithou bushings d, and the tenons c are made tou with or without the ferrule c.

The object of thesebushings and ferrules is to secure a free and uniform action-of the slats, unaected by the weather. f is a case, in which are formed bearings to receive the round'portion of the bearing ot' the ilangeferrule g g. The gear tis secured upon the end of the ferrule g by soldering. The

anged portion g of this ferrule is placedV astride o'f the body of the slat h, and holds it from turning, except as it turns with the slat. iis a gear secured upon the end of the ferrule g. k is a ratchet-rod, which connects and plays in the gear t', and rotates simultaneously all the slats by means of a lever, m, secured to one of the ferrules g, between the case f and the end of the slat h. This case is secured in the rabbet of the stile by screws and stopper a.

By ythe use of these rabbets o the blindframes can-be made and finished before the slats are placed therein, and the slats can be readily removed at any time when desired, and transparencies, wire-gauze, fancy-figured net-work, scroll-work, or other desirable tilling may be inserted and removed at pleasure.

The case f is made in two parts, having prongs p fitting into recesses alternately over and under each other, which serve to keep the two surfaces llush one with the other. The slat-tenon bearings are formed in the same way as those in the case f. This twopart case f' is also provided with fastening or supporting bars. to be secured in the rabbet of the stile by screws and stops in the same way as the casef.

The gears are formed from tubing drawn in the shape shown by the gears, of "arious lengths, and cut up into the required thickness by a saw-machine, such as those in common use for cutting metal. Y

The ilange-ferrules are formed in one piece of metal, by machine, similar to the machines now in use for making cartridges.

These gears, because of their cheapness, are peculiarly adapted for various other purposes, as toys, &c. The iiange-ferrules'g g' re also adapted, because of their cheapness, or various other useful purposes. v

By this improvement I am enabled to greatly cheapen the manufacture and produce a more perfect article of manufacture and use. Y Y

Having thus set forth the nature, construction, and advantage of this improvement, what I claim, and desire t'o secure by Letters Patent, is

1. The gear t', formed of tubing, in combi- This case is designed v nation with a. flange-ferrule, g g', formed of gears z' and ratchet 1c, substantially as and for 011e piece of metal, and blind-Slat h, substantially as and for tho purpose set forth.

2. Tho ferrue e, in combination with the bushing d., stop b, and Slat h, substantially as and for the purpose set forth.

3. The two-part oase f', in combination with the purpose set forth.
